Abstract:
Young America: The Daguerreotypes of Southworth & Hawes (2005) is a monumental exhibition catalogue showcasing the work of Albert Sands Southworth and Josiah Johnson Hawes. Together the partners established a renowned daguerreotype studio in mid-nineteenth-century Boston that catered to the city’s bourgeoisie. This paper seeks to unravel the mystery of dozens of daguerreotypes found in Young America, in which elite Boston women appear to be nearly nude. The unidentified women stand in stark contrast to the carefully concealed bodies of Southworth & Hawes’ other female subjects. Why would they expose themselves in such a manner before the camera’s lens? This paper attributes the women’s state of (un)dress to their deliberate emulation of two sculptures in the classical tradition: Clytie, a marble bust dating to antiquity, and Proserpine, a mid-nineteenth-century marble bust by American neoclassical sculptor Hiram Powers. This argument first reveals how a general “classical statue” aesthetic prevailed for women’s deportment in antebellum America, then demonstrates that the busts of Clytie and Proserpine had special significance as icons of white, elite female beauty in the period. Next, this paper makes the case that Southworth & Hawes devised a special style of photography deriving from their own daguerreotypes of the two statues, in which the women’s off-shoulder drapery was deliberately obscured allowing their female clientele to pose in the guise of these famous statues. The paper concludes by arguing that the women shown in these images could pose in this style without contravening societal norms, as these mythological figures were construed by women and men in the period to reflect the central precepts of the mid-nineteenth-century “Cult of True Womanhood.” Moreover, the busts offered sartorial models that reinforced standards of female dress as they related to class and privilege. By baring their flawless, white skin, however, the women positioned themselves at the crux of contentious beliefs about race in a deeply divided nation prior to the American Civil War.

Abstract:
Green fluorescent proteins (GFPs) and calcium-activated photoproteins of the aequorin/clytin family, now widely used as research tools, were originally isolated from the hydrozoan jellyfish Aequora victoria . It is known that bioluminescence resonance energy transfer (BRET) is possible between these proteins to generate flashes of green light, but the native function and significance of this phenomenon is unclear. Using the hydrozoan Clytia hemisphaerica , we characterized differential expression of three clytin and four GFP genes in distinct tissues at larva, medusa and polyp stages, corresponding to the major in vivo sites of bioluminescence (medusa tentacles and eggs) and fluorescence (these sites plus medusa manubrium, gonad and larval ectoderms). Potential physiological functions at these sites include UV protection of stem cells for fluorescence alone, and prey attraction and camouflaging counter-illumination for bioluminescence. Remarkably, the clytin2 and GFP2 proteins, co-expressed in eggs, show particularly efficient BRET and co-localize to mitochondria, owing to parallel acquisition by the two genes of mitochondrial targeting sequences during hydrozoan evolution. Overall, our results indicate that endogenous GFPs and photoproteins can play diverse roles even within one species and provide a striking and novel example of protein coevolution, which could have facilitated efficient or brighter BRET flashes through mitochondrial compartmentalization.

Abstract:
Abstract This study represents a synthesis of recent faunistical results (2012-2015), regarding the Macrolepidoptera of Dobrogea (south-eastern Romania) (Fig. 1A). Records of species of great faunistical and zoogeographical importance for the Romanian fauna are included. Eublemma porphyrina (Freyer, 1844) is reported for the first time in the Romanian fauna. The presence of several species known in the country based exclusively on very old records is confirmed (e.g. Dryobotodes carbonis (F. Wagner, 1831), Eremodrina pertinax (Staudinger, 1879), Zekelita antiqualis (Hübner, [1809])). Certain rare species with few records are also presented, such as Catopta thrips (Hübner, 1818), Sphingonaepiopsis gorgoniades (Hübner, 1819), Grammodes bifasciata (Petagna, 1787), Clytie syriaca (Bugnion, 1837), Symira dentinosa Freyer, 1839, Chazaria incarnata (Freyer, 1838), Protarchanara brevilinea (Fenn, 1864), Polymixis rufocincta (Geyer, [1828]), Gortyna cervago Eversmann, 1844, Dichagyris melanura (Kollar, 1846), Polyommatus (Agrodiaetus) admetus (Esper, 1783), Libythea celtis (Laicharting in Fuessly, 1782), Kirinia roxelana (Cramer, 1777), etc. Several Macrolepidoptera species recorded for the first time in Dobrogea are also included, eg: Hyloicus pinastri (Linnaeus, 1758), Cyclophora quercimontaria (Bastelberger, 1897), Perconia strigillaria (Hübner, 1787), Dryobotodes carbonis (F. Wagner, 1831), Meganephria bimaculosa (Linnaeus, 1767), Cerastis leucographa ([Denis & Schiffermüller], 1775), Noctua janthe (Borkhausen, 1792). There are 602 Macrolepidoptera species listed in this work. The studied localities have not been, or have been only little investigated previously in terms of Lepidoptera fauna, eg: Creasta Cardonului-Hamcearca, Enisala (Tulcea County), Fântâniţa-Murfatlar, Allah Bair Hill, Esechioi Forest, Oltina, Şipotele (Constanţa County). The study also includes aspects of zoogeography, invasive species, protection of habitats and protection of endangered species.

Abstract:
Os ciclos de vida de Clytia linearis (Thornely, 1899) e de duas espécies apresentando caracteres considerados diagnósticos de Clytia gracilis (M. Sars, 1850) – aqui denominadas Clytia cf. gracilis sp. 1 e Clytia cf. gracilis sp. 2 – foram estudados com base em espécimes coletados no infralitoral raso da costa de São Sebastião e Ilhabela, sudeste do Brasil, entre fevereiro de 1999 e abril de 2000. Medusas foram cultivadas em laboratório, a temperatura de 22-24oC. Colônias de C. linearis são monossifônicas, simpodiais, com até 21,5mm de altura e portando até 26 hidrantes e 10 gonângios. Medusas adultas, alcançando 2,5-3,6mm de diâmetro e até 29 tentáculos e 28 estatocistos, podem ser distinguidas de outras espécies de Clytia pela presença de nematocistos microbásicos mastigóforos do tipo C. Medusas adultas de Clytia cf. gracilis spp. 1 e 2 podem ser distinguidas das demais espécies do gênero estudadas até o momento pela presença de uma fileira de nematocistos microbásicos mastigóforos do tipo A na umbrela, no nível do canal circular. Medusas adultas de C. cf. gracilis sp. 1 e C. cf. gracilis sp. 2 apresentam até 16 tentáculos e podem ser distinguidas entre si pelo diâmetro da umbrela: 6,6-10,1mm e 3,6-5,5mm, respectivamente. Quanto ao estágio de pólipo, C. cf. gracilis sp. 1 apresenta usualmente colônias dicotômicas eretas, hidrotecas alongadas, e gonotecas na hidrorriza e pedículos. Estes caracteres concordam com a descrição de C. gracilis, mas as espécies diferem entre si pela morfometria das gonotecas e dos nematocistos microbásicos mastigóforos do tipo B: aproximadamente 15mm de comprimento para C. gracilis e 9-10mm para C. cf. gracilis sp. 1. Por outro lado, nematocistos do tipo B de C. cf. gracilis sp. 2, com aproximadamente 14,5mm de comprimento, em média, são morfometricamente semelhantes aos de C. gracilis. No entanto, C. cf. gracilis sp. 2 difere de C. gracilis pela forma da hidroteca, por apresentar gonotecas apenas na hidrorriza, e pelo hábito polissifônico do colônias bem desenvolvidas. Uma terceira espécie, C. cf. gracilis sp. 3, é descrita com base em uma colônia sem gonângios. Aspectos da sistemática de Clytia são discutidos.
he life-cycles of Clytia linearis (Thornely, 1899) and two species with characters considered diagnostic of Clytia gracilis (M. Sars, 1850) – Clytia cf. gracilis sp. 1 and Clytia cf. gracilis sp. 2 – have been studied based on specimens collected in the shallow subtidal coast of São Sebastião and Ilhabela, southeast Brazil, between February 1999 and April 2000. Medusae were cultured in the laboratory (22-24oC). Colonies of C. linearis are monosiphonic, sympodial, up to 21.5mm high and bearing up to 26 hydranths and 10 gonangia. Adult medusae reached 2.5-3.6mm in diameter, and up to 29 tentacles and 28 statocysts. The presence of microbasic mastigophore type C nematocysts distinguishes adult medusae of C. linearis from other species of Clytia. A band of microbasic mastigophore type A nematocysts in the umbrella, at the level of the circular canal, distinguishes adult medusae of Clytia cf. gracilis spp. 1 and 2 from other species of the genus. Adult medusae of C. cf. gracilis sp. 1 and C. cf. gracilis sp. 2 have up to 16 tentacles, and can be distinguished by the diameter of the umbrella: 6.6-10.1mm and 3.6-5.5mm, respectively. Colonies of C. cf. gracilis sp. 1 are usually erect and dichotomous, the hydrothecae are elongated and the gonothecae present in the hydrorhiza and pedicels. These features closely match with the description of C. gracilis, but both species differ in the morphometry of the gonothecae and microbasic mastigophore type B nematocysts: about 15mm (length) for C. gracilis and 9-10mm for C. cf. gracilis sp. 1. Type B nematocysts of C. cf. gracilis sp. 2 (about 14.5mm in length) are more similar in size to those of C. gracilis. However, the former species differs from the latter in the shape of the hydrothecae, by having gonothecae only at the hydrorhiza and polysiphonic well-developed colonies. A third species, C. cf. gracilis sp. 3, is described based on an unfertile colony. Aspects of the systematics of Clytia are discussed.

Abstract:
Un contrôle précis de la maturation ovocytaire et de la ponte sont essentiels au succès de la reproduction sexuée au sein le règne animal. Ces processus sont coordonnés précisément par des signaux endocriniens et/ou environnementaux, selon les espèces, mais beaucoup reste à apprendre sur leurs régulations. Chez les cnidaires, de nombreuses méduses du groupe des hydrozoaires sont connues pour produire des gamètes en réponse à la transition nuit/jour. Pour caractériser les machineries cellulaires et moléculaires liant la réception de la lumière à l'initiation de la maturation ovocytaire, j'ai étudié la méduse hydrozoaire Clytia hemisphaerica. Mon travail de thèse s’est découpé en trois parties, chacune impliquant l'identification d'un composant moléculaire clé de ce processus.Mon étude initiale faisait partie d'une collaboration avec N. Takeda (Asamushi) et R. Deguchi (Sendai), chercheurs qui avaient, avant le début de ma thèse, identifié chez Clytia les Hormones d'Incitation de Maturation ovocytaire endogènes (MIH) comme étant des tétrapeptides de type WPRPamide, produit par clivage de deux précurseurs à neuropeptides. J'ai montré par hybridation in situ et immunofluorescence que les deux gènes précurseurs du MIH sont exprimés par un type de cellules neurosécrétrices localisées au niveau de l’ectoderme de la gonade, et que les peptides MIH sont sécrétés par ces mêmes cellules suite à une stimulation lumineuse. Cette étude a posé les bases permettant l'identification des régulateurs agissant en amont et en aval du MIH, et plus spécifiquement ceux impliqués dans la photoréception de l’ectoderme de la gonade et la réception du MIH par les ovocytes.Pour identifier le récepteur du MIH de Clytia (CheMIHR) dans les ovocytes, j'ai compilé à partir de données transcriptomiques issues de tissus de gonades, une liste de 16 protéines candidates de la famille des Récepteurs Couplés aux Protéines G (GPCR). J'ai cloné les 16 cDNAs et, utilisant une méthode de « deorphelinisation » de GPCR basée sur de la culture cellulaire (collaboration avec P. Bauknecht et G. Jékély; MPI, Tübingen), j’ai pu identifier un GPCR activée par des peptides MIH synthétiques. Sa fonction in vivo comme récepteur essentiel du MIH a été confirmée par la méthode d'édition génétique CRISPR/CAS9. La délétion ainsi produite, entraînant un déplacement du cadre de lecture au sein du gène CheMIHR, a détérioré la croissance des colonies de polypes et le comportement de ponte des méduses matures. Confirmant la fonction de CheMIHR, la maturation ovocytaire chez des mutants CheMIHR ne pouvait pas être déclenchée par la lumière ou par addition de MIH synthétiques, mais pouvait être rétablie en utilisant des analogues au cAMP, molécule connue pour agir en aval de la réception du MIH dans les ovocytes d’hydrozoaires. Des analyses phylogénétiques ont montré que Clytia MIHR est affilié à un sous-ensemble de familles de neuropeptides de bilaterians impliqués dans divers processus physiologiques, notamment la régulation de la reproduction. Des hybridations in situ sur les méduses Clytia, ont en outre montré l'expression des précurseurs de CheMIH et de CheMIHR dans des cellules neurales hors de la gonade, suggérant un rôle plus large du couple CheMIH-MIHR que la seule initiation de la maturation ovocytaire.Pour mieux comprendre la photoréception des gonades chez Clyita, j'ai montré que la ponte est sélectivement incitée par la lumière bleu-cyan, et mis en évidence, grâce à l’analyse de données de transcriptome de gonade, qu’un photopigment de la famille des Opsin (Opsin9) est hautement exprimé dans l'ectoderme. De façon saisissante, les hybridations in situ ont montré que le gène Opsin9 est exprimé dans les mêmes cellules sécrétant le MIH. L'introduction d'une mutation de changement de cadre de lecture dans le gène Opsin9 via la technologie CRISPR/Cas9 a empêché la maturation ovocytaire et la ponte des méduses mutantes en réponse à la lumière
Tight control of oocyte maturation and of gamete release is essential for successful sexual reproduction in the animal kingdom. These processes are precisely coordinated by endocrine and/or environmental cues, depending on the species, but much remains to be learned about their regulation. Within the Cnidaria, many hydrozoan jellyfish are known to spawn mature gametes following dark/light transitions. To characterise the cellular and molecular machinery linking light reception and oocyte maturation initiation, I have studied the hydrozoan jellyfish Clytia hemisphaerica. My thesis work had three parts, each involving the identification of a key molecular component of this process.My initial study was part of a collaboration with N. Takeda (Asamushi) and R. Deguchi (Sendai), who identified the endogenous oocyte Maturation-Inducing Hormones (MIH) in Clytia as WPRPamide-related tetrapeptides, generated by cleavage of two neuropeptide precursors. I showed by in situ hybridization and immunofluorescence that Clytia MIH is produced by neurosecretory cells of the gonad ectoderm that co-express the two precursor genes, and that it is secreted upon light stimulation. This study paved the way for identification of regulators acting upstream and downstream of MIH release in the gonads, specifically the ones involved in photoreception in the gonad ectoderm, and in MIH reception by the oocytes. To identify the Clytia MIH receptor (CheMIHR) in the oocytes, I compiled a shortlist of 16 candidate G protein-coupled receptors (GPCRs) from gonad transcriptome data. I cloned all 16 cDNAs and, using a cell culture-based "GPCR deorphanization" assay (collaboration with P. Bauknecht and G. Jékély; MPI, Tübingen), identified one GPCR that was activated by synthetic MIH peptides. Its in vivo function as the essential MIH receptor was confirmed by CRISPR/Cas9 gene editing. Introduction of a frame-shift mutation in the CheMIHR gene impaired growth of Clytia polyp colonies and also the spawning behaviour of mature medusae. Confirming the function of CheMIHR, oocyte maturation in CheMIHR mutants could not be triggered by light or by synthetic MIH, but could be restored using cell-permeable analogues of cAMP, known to act downstream of MIH reception in hydrozoan oocytes. Phylogenetic analyses showed that Clytia MIHR is related to a subset of bilaterian neuropeptide hormone receptor families involved in diverse physiological processes, including regulation of reproduction. Accordingly, in situ hybridization showed the expression of Clytia MIH precursors and MIHR in non-gonadal neural cells, suggesting a wider role of Clytia MIH-MIHR besides oocyte maturation initiation.To address gonad photoreception, I showed that Clytia spawning is selectively induced by blue-cyan light, and then identified using gonad transcriptome data an opsin photopigment (Opsin9) highly expressed in the ectoderm. Strikingly, in situ hybridization showed that Opsin9 is expressed in the MIH-secreting cells. Introduction of a frame-shift mutation into the Opsin9 gene via CRISPR/Cas9 prevented oocyte maturation and spawning of mutant jellyfish in response to light. Anti-MIH immunofluorescence and rescue experiments with synthetic MIH showed that the essential function of Opsin9 is upstream of MIH release. Spawning in Clytia thus appears to be regulated by a dual function photosensory-neurosecretory cell type, perhaps retained from a distant metazoan ancestor

Chez les métazoaires, les premières phases du développement embryonnaire sont assurées par des facteurs maternels de nature variée. Accumulées et positionnées dans l’œuf au cours de sa formation, ces molécules constituent les ressources en nutriments nécessaires et les informations permettant de gouverner la mise en place du plan d’organisation de l’embryon. Cette thèse illustre le rôle fondamental de facteurs maternels dans le développement embryonnaire chez le cnidaire Clytia hemisphaerica à travers trois volets. Le premier aborde le phénomène de localisation des ARNs. A la suite de la découverte des ARNs déterminants CheFz1, CheFz3 et CheWnt3, de nouveaux ARNs maternels, localisés dans l’œuf de Clytia selon différents patrons, ont été identifiés. L’étude des mécanismes de localisation de ces ARNs a été débutée par une première analyse des séquences 3’UTRs et l’observation du comportement d’ARNs fluorescents injectés dans les ovocytes en cours de maturation. Le deuxième volet concerne la protéine centriolaire Poc1, qui chez Clytia hemisphaerica a une localisation centrosomale et est nécessaire pour assurer les divisions cellulaires et la gastrulation. Le troisième volet concerne les protéines fluorescentes GFP et les photoprotéines Clytines. Chez Clytia, un gène GFP ainsi qu’un gène Clytine sont spécifiquement exprimés dans les ovocytes et leurs protéines co-adressées aux mitochondries. Un transfert d’énergie in vivo a été mis en évidence dans les œufs, indiquant un couplage fonctionnel des deux protéines maternelles. Dans l’ensemble, ce travail a fourni de nouvelles connaissances concernant la phase maternelle du développement chez une espèce modèle émergente

Abstract:
La méduse hydrozoaire Clytia hemisphaerica a une plasticité lui permettant de répondre efficacement à différents types de blessure. Au cours de ma thèse, je me suis intéressée aux processus cellulaires et moléculaires au cours de la régénération de l’organe digestif regroupant la bouche et l’estomac (appelé ‘manubrium’) chez cette méduse. J’ai pu observer que la réponse à la blessure se décompose en trois phases successives : la cicatrisation, le remodelage de l’ombrelle rétablissant la forme méduse et la régénération de certains des organes manquants. La régénération du manubrium repose sur la formation d’une zone de prolifération locale et sur des migrations de cellules souches venant des gonades. Des éléments structuraux, notamment les fibres musculaires, jouent un rôle clef dans le repatterning de l’ombrelle et la position du manubrium régénéré. J’ai également généré des données transcriptomiques des premiers stades de la régénération. Ces données ont permis d’identifier des marqueurs de différents types cellulaires du manubrium, et d’observer leur réapparition séquentielle au cours de la régénération. Elles ont également révélé que la voie Wnt/β-caténine est la voie de signalisation présentant l’expression la plus dynamique dans le manubrium en régénération, jouant très certainement un rôle important dans la régénération de cet organe. Les travaux réalisés confirment le potentiel de la méduse Clytia comme modèle de régénération permettant d’adresser de nombreuses questions sur le plan cellulaire et moléculaire, et ainsi de mieux comprendre l’évolution des mécanismes de régénération chez les métazoaires
The hydrozoan jellyfish Clytia hemisphaerica displays very efficient wound repair mechanisms after different types of injury. During my PhD, I investigated in the medusa the cellular and molecular processes involved in the regeneration of the feeding organ, called ‘manubrium’, ensuring the function of the mouth and stomach. I could define three successive phases during the wound response: wound healing, remodeling of the umbrella allowing the rapid recovery of the circular medusae shape, followed by the regeneration of some of the missing organs. Manubrium regeneration relies on local proliferation as well as cell migration from the gonads. Structural elements, especially the muscle fibers, play a key role in the repatterning process of the umbrella and the site of manubrium regeneration. I also generated transcriptomic data covering the early steps of regeneration. These data allowed the identification of markers of different cell types of the manubrium and documentation of their sequential reappearance during regeneration. They also revealed dynamic expression profiles for Wnt/β-catenin pathway components in the regenerating manubrium, strongly suggesting important roles for this pathway during regeneration. This work confirmed the potential of Clytia medusae as an experimental model for studying regeneration, allowing conserved cellular and molecular mechanisms to be uncovered, and our knowledge about the evolution of regeneration mechanisms in metazoans to be expanded

Abstract:
L'Hydrozoaire Clytia hemisphaerica présente un cycle de vie triphasique, typique des hydrozoaires, comprenant une colonie de polypes à propagation végétative et une forme nageant librement, la méduse qui est se reproduisent de façon sexuée. Les méduses mâles et femelles se reproduisent quotidiennement, déclenchées par la lumière et environ un jour après la fécondation, une larve planula ciliée se forme. Après trois jours, la planula se fixe sur le substrat et se métamorphose pour donner naissance à un polype fondateur de la colonie, destiné pour l’alimentation, le gastrozooïde. La colonie se propage par extension du stolon et un deuxième type de polype, le gonozooïde, libère des méduses par bourgeonnement. L'analyse du génome et des transcriptomes à travers les trois principaux stades de vie de Clytia ont révélé des programmes d'expression génique spécifiques à chaque étape (Leclère et al. 2019, Nat Eco & Evo). Nous étendons maintenant cette comparaison au niveau des types cellulaire en utilisant la technologie du Single Cell RNA-seq chez la méduse et la larve de Clytia. Avec L. Leclère et S. Chevalier (LBDV), nous avons généré un atlas cellulaire de la méduse femelle en collaboration avec T. Chari et J. Gehring du laboratoire de L. Pachter et B. Weissbourd du laboratoire de D. Anderson à Caltech (Chari et al. 2021, Science Advances). L'analyse de l'atlas cellulaire de la méduse a révélé huit classes cellulaires, dont l'épiderme et le gastroderme, les cellules bioluminescentes, les ovocytes et les cellules souches multipotentes (I-Cells) des hydrozoaires et leurs dérivés tels que les cellules neurales, les nématocytes et les cellules glandulaires. L'analyse par hybridation in situ des profils d'expression ont révélé des sous-types non caractérisés auparavant, dont 14 sous-populations neuronales. L'analyse de la trajectoire de la lignée des nématocystes a révélé deux programmes transcriptionnels distincts au sein de cette classe cellulaire, une phase "nématoblaste", caractérisée par la production de la capsule du nématocyste, et la phase de différenciation du nématocyste, caractérisée par la production du nématocil.L’obtention du ScRNAseq pour la planula Clytia a nécessité l'optimisation des protocoles de dissociation, de fixation et de sélection des cellules (collaboration avec le groupe d'Arnau Sébé-Pedros, Barcelone). L’atlas cellulaire de la planula est constitué de 4370 cellules regroupées en 19 clusters cellulaires. Après une analyse des profils d'expression par hybridation in situ de gènes connus et nouveaux à trois stades de développement de la planula, nous avons pu attribuer des identités cellulaires et combiner les 19 clusters en 8 grandes classes cellulaires. Celles-ci correspondent aux deux couches de tissu épithélial classic chez les cnidaires, l'épiderme et le gastroderme, les cellules souches hydrozoaires (I-Cells), les nématocytes (cellules urticantes), les cellules neurales, les cellules neurosécrétrices aborales et des populations distinctes de cellules sécrétrices, les cellules muqueuses et les cellules excrétrices putatives (PEC).Cet atlas des types cellulaires de la planula de Clytia représente le premier atlas cellulaire d'une larve d'hydrozoaire et fournit la caractérisation de populations cellulaires non décrites auparavant ainsi que des informations supplémentaires sur les types cellulaires déjà connus. L'analyse comparative des deux atlas cellulaires a révélé des programmes transcriptionnels de nématocytes similaires entre les stades, indiquant que les deux étapes du développement des nématocytes persiste pendant les transitions du cycle de vie. Nous avons également pu identifier des types cellulaires exprimant les mêmes gènes chez les deux stades. Parmi ces gènes partagés, des sous-types cellulaires ont été trouvés uniquement dans la méduse. L'analyse des programmes d'expression génique a également révélé la présence de types cellulaires supposément spécifiques à chaque stade
The hydrozoan Clytia hemisphaerica displays a typical tri-phasic hydrozoan life cycle including a vegetatively propagating polyp colony and free-swimming medusa form as the sexually reproductive life stage. Male and female jellyfish spawn daily, triggered by light and after fertilisation a ciliated planula larva forms in about one day. After three days the planula settles and metamorphoses to give rise to a primary feeding polyp, the gastrozooid, founder of the polyp colony. The colony propagates by stolon extension and a second type of polyp, the gonozooid, releases medusa by budding. Analysis of the genome and the bulk transcriptome across the three life stages revealed specific gene expression programs for each stage (Leclère et al. 2019, Nature Ecology & Evolution). We are now extending this comparison to the level of individual cell types via single-cell RNA transcriptomics of Clytia medusa and larva. Together with L. Leclère and S. Chevalier (LBDV), we generated a female medusa cell atlas in collaboration with T. Chari and J. Gehring from L. Pachter’s lab and B. Weissbourd from D. Anderson’s lab at Caltech (Chari et al. 2021, Science Advances). Analysis of the medusa cell atlas revealed eight broad cell type classes including epidermis and gastrodermis, bioluminescent cells, oocytes and the hydrozoan multipotent stem cells (i cells) and their derivatives such as neurons, nematocytes and gland cells. In situ hybridisation analysis of expression patterns revealed previously uncharacterized subtypes including 14 neuronal subpopulations. Trajectory analysis of the nematocyte lineage revealed two distinct transcriptional programs within this cell class, a “nematoblast” phase, characterised by the production of the typical nematocyte capsule, and the nematocyte differentiation phase, characterised by the production of the nematocil apparatus. ScRNAseq for the Clytia planula required refinement of cell dissociation, fixation and sorting protocols (collaboration with Arnau Sebé-Pedros’ group, Barcelona). Our planula Cell Atlas consists of 4370 cells grouped in 19 cell clusters. Following in situ hybridisation expression patterns analysis of known and novel genes at three planula developmental stages we could assign cell identities and combine the 19 clusters in 8 broad cell classes. These correspond to the two cnidarian epithelial tissue layers, the epidermis and the gastrodermis, the hydrozoan stem cells (I-cells), the nematocytes (stinging cells), neural cells, aboral neurosecretory cells and distinct population of secretory cells, mucous cells and putative excretory cells (PEC). This Clytia planula Cell Types Atlas represents the first cell atlas of an hydrozoan larva and provides characterization of previously undescribed cell populations as well as further information on already known cell types. Comparison analysis of the two Cell Atlases revealed similar nematocyte transcriptional programs between stages indicating that the two distinct developmental programs persist during life cycle transitions. We could identify shared gene expression at the cell type level between life stages. Among those, further subtypes were only found in the adult. Analysis of gene expression programs also revealed the presence of putative stage specific cell types

Abstract:
This thesis investigates the long incumbency of Clyde Carr, Labour MP for Timaru between 1928 and 1962. Before entering politics, Carr was a minister in the Methodist and Congregationalist Churches, a journalist, an editor, a poet and a radio announcer. He served on the Christchurch City Council from 1922 to 1928. Carr's career is unique in New Zealand parliamentary history as the longest term by a backbench MP in a provincial town seat. Two approaches are taken to explain Carr's incumbency. Firstly, the historical and social nature of the Timaru electorate is described and compared with nine other provincial town electorates. Timaru was characterised by slow population growth and high levels of union is at ion in the period, and both these factors were statistically associated with a high Labour vote in provincial town electorates. The high level of residential segregation in Timaru may also have acted to consolidate Labour support there. Secondly, Carr's behaviour at his eleven successful election campaigns in the seat is described. Carr's idiosyncratic political style and personal charisma were instrumental in his success in holding the seat, especially at elections where the country as a whole swung away from Labour. Six themes characterise Carr's political thought and behaviour: diligent constituency work, a natural ability to communicate in a wide range of contexts, innovative and active campaigning at elections, a "common touch", frequent involvement in controversy of one kind or another, and good fortune.

Abstract:
Ma thèse a porté sur le rôle d’ARPP19, une protéine qui est au cœur du mécanisme de reprise de la méiose des ovocytes. Chez tous les animaux, la méiose des ovocytes s’interrompt en prophase I. Ce long arrêt est mis à profit par l’ovocyte qui accumule des molécules nutritives et informatives utilisées lors de l’embryogenèse. L’arrêt en prophase est dû au maintien sous une forme inactive du MPF (M-phase Promoting Factor). Ce complexe, formé de la kinase Cdk1 et de la Cycline B, est le moteur de la division des cellules eucaryotes. Chez les vertébrés, une activité élevée de la kinase PKA (Protéine Kinase dépendant de l’AMPc) empêche l’activation du MPF, ce qui maintient le blocage en prophase de l’ovocyte. Un stimulus hormonal provoque la levée de ce blocage et la reprise de la méiose. Chez les vertébrés, l’un des premiers évènements induits par cette stimulation est l’inactivation de PKA, ce qui enclenche une voie de signalisation aboutissant à l’activation du MPF. Ma thèse a porté sur les mécanismes permettant à PKA de contrôler le MPF. Chez le Xénope, l’un des substrats-clés de PKA est ARPP19, phosphorylée par PKA sur la sérine 109 (S109). Suite à l’inactivation de PKA par la stimulation hormonale, ARPP19 est déphosphorylé par la phosphatase PP2A-B55 et permet indirectement l’activation du MPF. Au moment où le MPF s’active, ARPP19 remplit une autre fonction. Le MPF active la kinase Greatwall (Gwl) qui phosphoryle ARPP19 sur la sérine 67 (S67), le convertissant en un inhibiteur de PP2A-B55. Cette inhibition est essentielle pour la division car cette phosphatase s’oppose au MPF en déphosphorylant ses substrats. Le contrôle négatif exercé par PKA sur le MPF n’est pas conservé chez tous les métazoaires. De nombreuses espèces non-vertébrées présentent un mécanisme inversé : la levée du blocage en prophase ne dépend pas d’une inactivation, mais d’une activation de PKA, comme chez la méduse Clytia hemisphaerica. Or, ARPP19 est exprimé dans les ovocytes de cette espèce. La protéine devrait donc être phosphorylée par PKA dans l’ovocyte de Clytia. Comment ne bloque-t-elle pas l’activation du MPF? J’ai montré qu’ARPP19 de Clytia (ClyARPP19) possédait un site de phosphorylation par PKA. Néanmoins, ClyARPP19 est un mauvais substrat de PKA et n’est pas phosphorylé par cette kinase dans l’ovocyte. En outre, les mécanismes par lesquels il inhibe le MPF ne sont pas fonctionnels chez Clytia. Une double sécurité protège donc l’ovocyte de Clytia d’une inhibition du MPF par ARPP19. Mes résultats permettent d’établir un scénario évolutif quant au contrôle négatif exercé par PKA sur la reprise de la méiose chez les vertébrés. Contrairement au contrôle d’ARPP19 par Gwl, retrouvé chez tous les eucaryotes, le site de phosphorylation d’ARPP19 par PKA apparaît chez les métazoaires, chez qui il est conservé. Mais il n’est utilisé comme régulateur de la reprise de la méiose que chez les vertébrés, grâce à un accroissement de son potentiel de phosphorylation par PKA. J’ai ensuite étudié les mécanismes permettant à la forme phosphorylée sur S109 d’ARPP19 d’inhiber le MPF. J’ai découvert qu’en prophase, ARPP19 est faiblement phosphorylé sur la S67 par une activité basale de Gwl. Or, il est critique de limiter cette phosphorylation pour éviter une reprise spontanée de la méiose. J’ai montré que deux types de régulation limitaient cette phosphorylation. Le premier est la phosphorylation de la S109 par PKA, le second est une régulation intramoléculaire reposant sur deux domaines de la partie C-terminale d’ARPP19. Mes travaux conduisent à une nouvelle vision de l’arrêt en prophase, un état métastable où ARPP19 est à la fois phosphorylé sur S109 (majeure) et S67 (mineure). Ils permettent de dégager un rôle négatif de la phosphorylation d’ARPP19 par PKA sur l’activation du MPF : empêcher la phosphorylation par Gwl. La déphosphorylation de la S109 en réponse à l’hormone génère une protéine ARPP19 accessible à Gwl, l’un des éléments nécessaires à l’activation du MPF
My thesis focused on the role of ARPP19, a protein at the center of meiosis resumption in oocytes. In all animals, oocyte meiosis is interrupted during prophase I. This long pause is used by the oocyte to accumulate nutritive and informative molecules that will serve during embryogenesis. The prophase arrest is due to an inactive form of MPF (M-phase Promoting Factor). This complex, made up of the Cdk1 kinase and Cyclin B, is the driving force behind eukaryotic cell division. In vertebrates, high levels of cAMP-dependent protein kinase (PKA) activity prevent MPF activation, keeping the oocyte blocked in prophase. A hormonal stimulus releases the prophase arrest and promotes meiosis resumption. In vertebrates, one of the first events induced by this stimulation is the inactivation of PKA, triggering a signaling pathway leading to MPF activation. My thesis focused on the mechanisms by which PKA controls MPF. In Xenopus, one of PKA key substrates is ARPP19, phosphorylated by PKA on serine 109 (S109). Following inactivation of PKA by the hormonal stimulation, ARPP19 is dephosphorylated by the PP2A-B55 phosphatase, indirectly enabling MPF activation. When MPF activates, ARPP19 undertakes another function. MPF activates the Greatwall kinase (Gwl), which phosphorylates ARPP19 on serine 67 (S67), converting it into an inhibitor of PP2A-B55. This inhibition is essential for division, as this phosphatase opposes MPF by dephosphorylating its substrates. The negative control exerted by PKA on MPF is not conserved in all metazoans. Many non-vertebrate species show an inverted mechanism: the release of the prophase block does not depend on PKA inactivation, but on its activation, as in the jellyfish Clytia hemisphaerica. ARPP19 is expressed in the oocytes of this species. The protein should therefore be phosphorylated by PKA in the Clytia oocyte. Why does it not block MPF activation? I have shown that Clytia ARPP19 (ClyARPP19) has a PKA phosphorylation site. However, ClyARPP19 is a poor substrate of PKA and is not phosphorylated by this kinase in the oocyte. Moreover, the mechanisms by which it inhibits MPF are not functional in Clytia. This double security level therefore protects Clytia oocyte from MPF inhibition by ARPP19. My results provide an evolutionary scenario for the negative control exerted by PKA on the resumption of meiosis in vertebrates. Unlike the control of ARPP19 by Gwl, conserved in all eukaryotes, the phosphorylation site of ARPP19 by PKA appears in metazoans, where it is conserved. But it is used as a regulator of meiosis resumption only in vertebrates, thanks to an increase of its phosphorylation potential by PKA. I then investigated the mechanisms by which the phosphorylated form of ARPP19 on S109 inhibits MPF. I discovered that in prophase, ARPP19 is weakly phosphorylated on S67 by a basal Gwl activity. Limiting this phosphorylation is critical to prevent spontaneous resumption of meiosis. I have shown that two types of regulation limit this phosphorylation by Gwl. The first is S109 phosphorylation by PKA, the second is an intramolecular regulation based on two domains in the C-terminal part of ARPP19. My work leads to a new vision of the prophase arrest, a metastable state in which ARPP19 is phosphorylated on both S109 (major) and S67 (minor). They provide insight into one negative role of PKA-phosphorylated ARPP19 on MPF activation: preventing phosphorylation by Gwl. Dephosphorylation of S109 in response to the hormone generates an ARPP19 protein accessible to Gwl, one of the key elements required for MPF activation

Abstract:
[Extract from Foreword] This ‘cruise report’ is the first of a short series, reflecting the aspiration of the Clyde Fishermen’s Association to establish a rigorous sampling scheme to monitor changes in the abundance and distribution of cod (and later other gadoid species) within the Clyde area. The Scottish Oceans Institute was approached to provide independent scientific support in early 2016. A series of surveys was then conducted in 2016, 2017 and 2018. In each survey the SOI provided observers, collected data and wrote up a cruise report detailing the methods used and the location, numbers, weights, sex and maturity states of fish caught. Trials were halted after 2018 firstly because of pressing issues resulting from Brexit which absorbed any potentially available human and other resources, and secondly because of the COVID pandemic. The reports remained as unapproved and incomplete drafts until 2022. Picking up these reports again in 2022, we have responded to reviewers’ comments since made by Marine Scotland Science and have finalised all four reports in the 2016-2018 current series.
